Good Suggestion Gupta but unfortunately issue persists

Just worked for me - thanks, Gupta

I'm seeing this issue on a couple Macs running 10.12.x. The instructions from @gupta1991ravi above doesnt appear to resolve the issue for me.

Does the Dictation download package come from SUS or another Apple server? I see a "Dication Language Update 2.0.4" (031024486) on my SUS server, but it keeps geting disabled for some reason (everytime I enable it it gets disabled again later automatically).

Are the Apple Dictation packages(s) available ala carte from Apple? I can't find them.

I downloaded Install SpeechRecognitionCoreLanguage_en_US2.0.4.pkg and put it in self service for our users @dstranathan

Thanks @CasperSally - where did you find the .pkg at? I'm unable to locate it.

During the install on a machine running High Sierra, I was able to hard link it out of /Library/Updates/031-06400/SpeechRecognitionCoreLanguage_en_US.pkg to keep a copy for future use.

Out of interest , does anyone that's having issues here also have an Antivirus installed? Microsoft's Endpoint Protection in particular?

Just an update on this , incase anyone else runs into the issue . I found that my problems were caused by my internal SUS server . If I changed to the Mac to point to Apple , all seemed to work ok .
